Captain Mac (マック, Makku?) is a minor character from Final Fantasy Mystic Quest. He is Kaeli's father, and sails a ship in the lake between Windia and Aquaria. When the lake dries up, he is stranded, but is able to survive long enough for Benjamin and Reuben to re-flood the lake by blowing a hole in Spencer's Place. His ship floats back to the docks at Windia, but is full of monsters.
The heroes board the ship and defeat the monsters, but when they reach Mac, he warns them that he has discovered a missing piece of the prophecy which refers to the Dark King. He then lends Benjamin his ship so that he and Phoebe can travel to the base of the Focus Tower and climb to the very top to defeat the Dark King. Even after the Dark King is defeated, Mac allows Benjamin to keep his ship.
